UI improvements - Instead of just saying locked on the levels that are locked, they specify what level you will need to be in order to play the level.

Notifications -tells you when you unlock a new level while you are playing.

With these grand improvements, I am excited to start work on levels 6-10. If anyone has any ideas that would improve Battle Ball or other games of mine, feel free to leave a comment here or at kongregate. My kongregate username is Tiuipuv.
Cheers,
